What is the minimum amount of thermal coating allowed missing from a Mk 65 case without requiring repair?

The minimum amount of thermal coating allowed to be missing from a Mk 65 case without requiring repair is specified as less than 1 square inch. This standard is critical because the thermal coating plays a vital role in protecting the integrity of the case during storage and handling, particularly from environmental factors and potential corrosion.

In this context, if the damage to the thermal coating is minimal—quantified as less than 1 square inch—this amount is considered acceptable and does not compromise the overall safety or functionality of the munitions. Allowing a threshold of less than 1 square inch enables operational flexibility, where minor wear may occur without necessitating excessive repair processes for small blemishes, ultimately ensuring that munitions remain serviceable under normal conditions.

Situations that involve larger areas of missing thermal coating would indeed require further inspection and potentially repair due to the heightened risk of exposing the underlying materials to adverse conditions or degradation.
